Dupilumab improves alcohol tolerance in aspirin-exacerbated respiratory disease

Biologics Reduce Symptoms of Alcohol Intolerance Better than Aspirin Desensitization in Patients with N-ERD and Nasal Polyps

BACKGROUND

Non-steroidal anti-inflammatory drugs (NSAIDs) exacerbated respiratory disease (N-ERD) is associated with chronic rhinosinusitis with nasal polyps (CRSwNP), asthma, and NSAID hypersensitivity. An overproduction of leukotrienes characterizes the pathomechanism of the disease. N-ERD patients often report breathing difficulties after consuming alcohol. These symptoms have been observed in patients receiving either aspirin therapy after desensitization (ATAD), therapy with the biologics dupilumab (anti-IL-4Ra antibody) and omalizumab (anti-IgE antibody), or intranasal corticosteroid treatment (INCS).

METHODS

This retrospective, real-world study assessed the severity of alcohol-related and non-alcohol-related respiratory symptoms in CRSwNP/N-ERD patients 3-6 months after ATAD, biologic (dupilumab or omalizumab), or INCS therapy. A total of 171 patients (98 women and 73 men) were enrolled in the study. All groups received standard INCS therapy. Sixty-three patients were treated with ATAD; 48 received biologics (dupilumab n = 31; omalizumab n = 17); and 60 received INCS only and served as a control group. Alcohol-dependent symptoms and typical CRS symptoms (alcohol-independent) were quantified using visual analog scales (VAS).

RESULTS

ATAD and biological therapy significantly reduced VAS scores for alcohol dependence and CRS symptoms. In the control group receiving INCS, only non-alcohol dependent CRS symptoms improved significantly (p < 0.05). The most significant differences in pre/post scores were observed in patients receiving dupilumab, with the most significant improvement in alcohol-dependent and CRS symptoms (dupilumab > omalizumab > ATAD).

CONCLUSIONS

This real-world study shows that alcohol-related respiratory symptoms are a relevant parameter in CRSwNP/N-ERD patients. Patients benefit more from biologic therapy than from ATAD in terms of their alcohol-related symptoms and other CRS symptoms. Future studies should include placebo-controlled oral alcohol challenge.

Aspirin-exacerbated respiratory disease: Updates in the era of biologics

OBJECTIVE

Aspirin-exacerbated respiratory disease (AERD) is a chronic respiratory condition characterized by severe chronic rhinosinusitis with nasal polyps (CRSwNP), eosinophilic asthma, and respiratory reactions to cyclooxygenase inhibitors. The management of AERD has evolved recently with the availability of respiratory biologics for treatment of severe asthma and CRSwNP. The objective of this review is to provide an update on the management of AERD in the era of respiratory biologic therapy.

DATA SOURCES

A literature review of pathogenesis and treatment of AERD, with a specific focus on biologic therapies in AERD, was performed through publications gathered from PubMed.

STUDY SELECTIONS

Original research, randomized controlled trials, retrospective studies, meta-analyses, and case series of high relevance are selected and reviewed.

RESULTS

Aspirin therapy after desensitization (ATAD) and respiratory biologic therapies targeting interleukin (IL)-4Rα, IL-5, IL-5Rα, and immunoglobulin E, all have some efficacy in the treatment of CRSwNP and asthma in patients with AERD. There are currently no head-to-head studies comparing ATAD vs respiratory biologic therapy, or specific respiratory biologics, for asthma and CRSwNP in patients with AERD.

CONCLUSION

Advances in our understanding of the fundamental drivers of the chronic respiratory inflammation in asthma and CRSwNP have led to the identification of several potential therapeutic targets for these diseases that can be used in patients with AERD. Further study of the use of ATAD and biologic therapy, independently and together, will help to inform future treatment algorithms for patients with AERD.
